Materials to be used: Mblock 3 program, pinoo control card, 1 red led module, 1 yellow led module, 2 dc motors, soil moisture sensor.
Materials Required for Design: Forex, scissors and utility knife, 2 propellers, glue gun and silicone.
Project Construction:
Let's start with the design of the dryer for our project.
We cut 2 pieces of 15x10 cm, 10x20 cm, 20x15 cm from the forex.
By combining these parts, we create a bit platform.
We open a hole in the middle of the back of the platform with a utility knife, through which the cable of the soil moisture sensor can enter.
We pass the cable of the soil moisture sensor through the hole and silicon the sensor to the platform.
We silicon the red led module to the left at the top of the platform and the yellow led module to the right.
We silicone 2 propellers to the ends of dc motors.
We silicon the dc motors at an oblique angle, facing the soil moisture sensor at the top of the platform.
We attach the cables of the DC motors to the connection points, the red LED module to the 2nd Door, the yellow LED module to the 1st Door, and the soil moisture sensor to the 7th Door.
We plug the USB connection cable into the Pinoo card and the computer.
Adding Pinoo extension:
From the Extensions tab, click "Manage Extensions".
In the window that opens, we write “Pinoo” in the search engine and it is enough to say download to the result. Installed on our computer.
Connecting the Pinoo control board to the computer:
In Mblock 3, we click on the "Connect" tab in the upper left. In the window that opens, we click on the "Serial Port" section and select the "COM4" option from the page that opens.
NOTE: As each computer has different port entries, the numbers next to COM may change.
Click on the Cards tab. From the window that opens, we select the "Arduino Nano" card option used by the Pinoo control card.
Click on the Extensions tab. In the window that opens, we select "Pinoo", the extension of the control card we use.
Click on the Connect tab. Click "Firmware Update" from the window that opens.
Coding part:
When the green flag is clicked, we are constantly writing the codes that will show the value of the soil moisture sensor attached to the 7th door on the screen. Here we will see the value of 1023 in the first place. When we wet a paper towel and touch it on the soil moisture sensor, we will see that the values on the screen change.
If not, we add the structure from the control menu. We write our terms. 7. The value of the soil moisture sensor attached to the door is less than 710, that is, it is wet.
Repeat until we are from the control menu, we flow the code block and add our condition. Our condition is 7. We will repeat the process until the soil moisture sensor attached to the door is greater than 710, that is, until the wetness reaches a dry value.
First, we run the dc motors. Then we make the yellow led go out by lowering its status.
In order for the red led to flash, we first set the status of the led attached to the 2nd door to high and wait for 0.2 seconds, then turn off the state of the led by making it low and keep it waiting for 0.2 seconds.
If not, we first stop the dc motors.
After stopping the dc motors, we make the status of the red led attached to the 2nd door low and turn it off. Then, we make the yellow led attached to the 1st door turn on by making its status high.
In order to upload our codes to the Pinoo control card, we make the "Pinoo Program" command as our event starter and delete the code we used to display the soil moisture value on the screen.
Right-click on the “Pinoo Program” command and in the window that opens, “Install to Arduino” We select the option.
On the page that opens, we click on the "Upload to Arduino" button, which is selected in blue. Our codes are uploaded to our Pinoo control card.
After the “Installation Finished” message comes, click the “Close” button.
Working Status of the Project:
We insert the 9V battery.
At first, only the yellow led will light up. When we put a wet towel on the soil moisture sensor, the dc motors will start and the red LED will flash.
